Assignment: Molecular Shapes
The shape of a molecular can be determined by applying the VSEPR theory and
wave mechanics. In this assignment, demonstrate your understanding of the
molecular shapes of some common molecules by completing a problem set.
Instructions
Your task is to complete the questions in the problem set. Carefully read the
questions and provide thorough answers, including any Lewis structures, sketches,
or bond angles, where required.
Questions
1. Predict the Lewis structure and bond angles for each of the following molecules:
(2 marks each)
 C Cl

4(s)
 HgBr
2(s)
 SnBr
4(s)
2. Using VSEPR Theory, name and sketch the molecular shape of each of the
molecules listed in the first question. (2 marks each)
3. Draw the Lewis structure of the nitrite ion (NO
